Because lib/test_printf.c wants to use no_hash_pointers for testing
purpose, and lib/test_printf.c might be built as a loadable kernel module.
That is, no_hash_pointers is not meant for general use.

  config TEST_PRINTF
  	tristate "Test printf() family of functions at runtime"

  obj-$(CONFIG_TEST_PRINTF) += test_printf.o
